The shaft 68 isalso mounted to have Vrotative inoveinentand ,axial aietihent in `a bearing :72 the brakt- The driving mechanism (Figirres lto 5) eonsistsioit a rlrivingsliaft 73 `.unen -Wliiohtlie pulley `l?.fixed vand to .which the inotog. may be operatively connected by a gear74 on said shaft meshing with a pinion on the shaft of the motor andsaid shaft 73 being operatively connected to a driven shaft 76journalled in the bracket 63 geared to the shaft 68 by a bevelled pinionT7 meshing with a bevelled gear 7S rotatably carried by a yoke 79 fixedupon the bracket 63 engaging in an annular groove 8O in the hub of saidgear, and mounted on the shaft 68 to rotate vith said shaft and permitof axial movement of the shaft relative to said gear by a key1 81engaging in a keyway iu said shaft 68.

As stated it is an object of the invention to provide driving means torevolve or rotate the closure applying devices varia le speeds, and forthis purpose variable speed gearing is interposed between the drivingand drive-n shaft 73, 76 respectively, comprising an elongated gear 82fixed ou the shaft 73 and an intermediate shaft 83 journaled in casingS6 fixed upon the bracket 63, said shaft having a. pinion 84 tiredthereon to mesh with gear S5 loose on the shaft 76. The intermediateshaft 88 carries gears Aof variable size thereon, shown as three mediatepinion and the gear 82 while main taining the other levers in positionwith the pinions carried thereby out of mesh with the gear 82 and theireofoperating lintermediate pinions. rlhis means comprises a plate S9slidably mounted upon the casing 86 having a series of slot-s 90 one foreach of the levers. This plate may be adjusted longitudinally as shownin Figure 5 with all of the levers engaging the upper edge of the plateand the pinions carried thereby in idle position, or the plate may 'beadjusted longitudinally so that one ofl the levers engages a slot 90,the slots being so located in the plate that when a lever engages in aslotthe other levers will be out of line with their co-operating slotsand engagev on top of the plate. The platev89 is adjusted by a lever 86pivot-ally mounted upon the casing 86 having a bifurcated end in which apin S9 projecting' laterally from the plate 89 and through an opening 90in the casing engages. The pinion carrying levers 88 are locked inposition when. engaging in a plate slot 90 by latches 91, there beingone latch provided for each lever as clearly shown in Figure 5. Themovement of the pinion 84 is transmitted to the` gear`85 fixed, as

at 92, to one member of a clutch the other member of which is fixed tothe shaft 76, said clutch being shown in a general way at B, andoperative by a lever 93 to couple and uucouple the gear 85 to the shaftT6 and thereby connect and disconnect the driving and driven shafts. Thedriving means are carried upon the bracket 63 mounted in fixed posit-ionupon the shaft 22 and by the arrangement of the driving` connection ofthe pinion shaft 68 carried by `the camand the bevelled gear 78 mountedthereon meshing with the pinion 77 on the driven shaftv76 the cam withthe closure applying devices may be adjusted longitudinally on the shaftQ2 without disturbing or breaking the driving connection between saiddevices and the driving means.

To feed closures to the closure applying devices a closure carryinghopper H is provided (Figure 1) supported by a bracket 94 fixed to thecam and by which the shaft 71 is rotatably supported, the closures beingdelivered from the hopper to an outlet chute C leading therefrom by aselector in the form of a. wheel 95 engaging in an open side of thehopper andlixed to a shaft 96 rotatably supported by the hopper' anddriven from the shaft 71 by a belt 97 passing around a sheave 98 on thelatter shaft and a sheave 99 on the selector shaft k96. -The hopperchute is positioned` with the outlet to engage in the groove 38'of asegmental portion 87 .of ahead 35 of a closure applying device carriedby a slide or casing 33 when the latter are in their `fully recededposition as shown in Figures 1, 12 and 13, the outlet of the chute beingynormally shut oft' by the wall of the groove' leading to a closure seatand as an opening in the wall of the groove is brought into registerwith the chuteY outlet during the rotative movement of the closureapplying devices a closure from the chute will enter tothe closure seat,the succeeding closure in the chute being prevented from .beingdelivered from the chute bythe wall of the groove being brought oppositeto the chute outlet. As a closure is delivered to its seat thesucceeding closure in the chute will be in Contact therewith and as theclosure applying .devices move away from the chute outlet there is apossibility that such succeeding closure will impart a rolling movementto the closure engaging the plate 40 and partially unseat the same. Toprevent this and cause the closure to seat relative to the plate L10 alinger 100 (Figures 12 and 13) is pivotally supported at one end in acut out portion of the side wall of the chute atthe'outlet end, as shownat 101, and yieldingly urged in a direction into the chute by a spring102, and as the closure applying devices pass such linger a closurewhich has not been seated relative to the plate 40 will be yieldinglylill ried lby a post 1104 Figure `i12) ixerl in the table21, itheiend ofthis .iingenbeing curved,

as shown at :10.5, and .normally engaging with lthe bottom of Athe4groene -38 and as .the

closure applying `.devices passfsaid linger it will engage a 4closure.delivered from the chute to ,the plate 4l@ and `po sitively .seat thesame 4relative.thereto and .in position torengage over `the openinginpthe receptacle on the ta-bleQt when `the closure applyngwdeviceYiszmcved to closure ,applying pesitn by the cam-aS. To remove `closureswhich mayllwe been lodged in the chute a portionnf the wall `of theLchute, as 106V, (Figures l :andclS-)Yis releasable, said section of thej chute .wall lbeing ,pivotally supportedl as at 10,71, and releasablyretained in position continguous to the side walls of the chute bylatches 108 pivotally supported at; opposite sides 4oiitlieichnteconnected :byfa Lbar .109 rotatably 1mounted by lugs y1:10 i on l thechute, and said latches V.retained Vin position vto engage "pins projacting laterally from-.the `movable chute section by springs-.1.11. Itwill be-noted that the-closurecanrying hopper is snpported `bye-the .cam.with the foutletjchute in fixed relation Lto .the closure apply-ing idevices and will participate in the adjustment ofthe ,camand closureapplying devices upon the .shaft without disturbing of .the

closure feeding means relative tothe `closure applying devices duringsuch adjustment, and without disturbing the drivingfconnectionbetweenthe closure selecting means `of the hopper and the driving means.

To `position vthe receptacles on the `table 24 yrelative to the closureapplyingdevices a wheel112 .is lined concentricallyto the table 2.4 to`rotate therewith l(Figurel 6.) with curvedperipheral recessesllarranged ,concentric vwith 4the `closure applyingidevices.

The receptacles are delivered from the table24 to the passageway formed by a pair of' strips 146 mounted on thetable 21 to have adjustment relative to each other to provide apassageway of different widths from which the receptacles may be removedby hand or delivered to suitable transferring means (not shown).

The receptacles, such as glass bottles, to which the apparatus isparticularly adapted to apply closures are invariably of different sizesor heights and as the mechanism is arranged to impart a predeterminedclosure applying movement to the closure applying devices carryingslides in applying a closure to a receptacle, should a receptacle ofgreater height than the space between the table 24 and the closureapplying devices for which the latter was adjusted a crushing force orpressure will be applied to the receptacles and the consequent breakageof theV same. To prevent the breakage of receptacles in this mannermeans are provided to permit of movement of the closure applying devicesrelative to the table when a pressure greater than a predetermined forceis applied to such devices to compensate for the inequality in the sizesof the receptacles. For this purpose the portion of the cam constitutingthe working or high portion of the cam, as shown at 48 in Figures 14,and 16, is adapted to have transverse movement of the body of the camwhen pressure greater than a predetermined force is applied thereto.This portion 48 of the cam is slidably mounted and is normally urged ina downwardly direction by a spring 133 with lugs 134 arranged on saidcam portion engaging with the cam proper and the working face of suchcam portion flush with the working portion of the cam proper as clearlyshown in Figure 15. This spring normally maintains the cam in thisposition. However, to maintain said cam portion in such position to bereleased when a pressure greater than a predetermined force is appliedthereto a roller 135 is rotatably carried by a pair of arms 136extending upward from said'cam portion to engage with a curved or camportion 137 of a lever or arm 138 pivotally supported at 139 'on abracket 140 mounted on the cam proper out of line or at one side of theplan of movement of the cam portion 48 to take up end thrust of said camportion. The curved end of this lever is arranged with a portion toextend down in front of the roller, said lever being yieldingly urged.tween the lever or arm 138 and an adjustable abutment 143 to increaseand decrease the tension of the spring. When a pressure greater than thepredetermined force is applied to the cam from the cam portion 48 by theclosure applying devices, which pressure is regulated by the spring 141,such cam portion will be moved against the tension of the spring 133,and the roller 135 forced against the curved end of the lever 135 movingthe lever laterally against the tension of the spring 141 and permittingupward movement of the cam section 48. As soon as the cam section 48 isrelieved of the excess pressure of the closure applying devices such camportion will be returned to initial position by the Vspring 133` and thepressure of the spring 141 on the lever or arm 138. The tension of thesprings 133 and 141 is such as to exert sufficient resistance to the camportion 48 as to cause the closure applying devices'to perform theirclosure applying function. A protecting shield 145 is mounted upon thecam to extend around the same.

To provide lubricant between the head 28 and the shaft 22 a bore orpassage 146 is drilled into the upper end of the shaft having lateraloutlets 147 to the contacting surface between said shaft and head, alubricant carrying cup 148 being in communication with said bore througha tubular stem 149 supported in an enlargement of the bore at the end ofthe shaft.
